CHOOSING THE RIGHT NOZZLE ORIFICE SIZE FOR YOUR MACHINE

The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the
orifice, the greater the restriction of water flowing through the machine. This causes the pressure to increase.
• Choosing a nozzle with too large an • Choosing a nozzle with too small an orifice will limit water flow
orifice will reduce operating pressure. and possibly create an excessive load on the machine.
